Spamhaus

[jsmith221]

Is there a way to prevent EE allocating Spamhaus block listed ip addresses to ones internet connection? Having to reboot my mobile data router or requesting delisting from Spamhaus every time this happens is a tedious chore. I'm beginning to dread trying to send emails!

Thanks in advance, Jim

Me too...

I switched from 3 to EE to get around this problem but EE does it too! Spamhaus is a real pain.

@jsmith221 : It's not EE; it's your SMTP.

What is it about my SMTP that is the problem?

It's the thing checking with Spamhaus.

If you're sending mail direct-to-MX then you're going to come up against this kind of problem.

You should be routing e-mail through your internet service provider or through a third-party e-mail service. For my part, I use AuthSMTP. I am not affiliated with AuthSMTP in any way other than being a happy customer of theirs.

@grsdev : What's "direct-to-MX" & how do you send to it? Normally one just sends using your email provider's SMTP server.

@XRaySpeX Direct-to-MX is when you bypass your provider's SMTP service and send directly to the recipient's inbound mail server (Mail eXchange = MX). For example, if you're running your own MX at home for your own domain it can also act as an outbound relay and will do the same job as your provider's SMTP service. The only problem with that is, the MX at the receiving end is going to see an inbound e-mail coming from a dynamic, end-user connection, which is almost 100% probably going to be junk sent by a bot. The e-mail therefore gets rejected.

If you want to have your own MTA at home then you should get it to relay through your provider's SMTP service.

I have this Spamhaus problem intermittently when I connect my desktop PC to the internet using my 4G router. I send email using the SMTP server that my ISP told me to use.

If the only thing I change is to connect to the internet using my land line then the Spamhaus blocking NEVER happens.

It seems to me that the only thing that is different in these two set-ups is the range of ip addresses that are allocated to me. Some of the mobile ones are in a Spamhaus block list. None of the land line ones are.

@jsmith221 : The diff is that:

• With fixed landline BB you get your own unique (at the time) public IP that you share with nobody.
• With the mobile network you get a public IP that you may share with many other as EE uses CGNET in order to conserve the quantity of IPs it gives out. Therefore there is the much greater chance of ending up with an IP that is or was once used by a spammer.
